R&D Project Manager (f/m)

Your role

Join a technology-driven journey with global impact by contributing to the development of solutions that enable scientists worldwide to work better, faster, and more sustainably. As part of our continued growth, we are strengthening our R&D center in Guyancourt and are recruiting an R&D Project Manager (f/m) to design the next generation of Milli‑Q® systems—the global benchmark in laboratory water purification, used in thousands of research centers, hospitals, and industrial sites around the world.

Reporting to the R&D Director, you will lead a multidisciplinary team of engineers and technicians to drive projects from feasibility through to market launch. You coordinate across multiple disciplines (chemistry, mechanics, hydraulics, electronics, and embedded software) and work closely with both internal and external partners, including Marketing, Industrialization, Project Purchasing, and the PMO.

During the feasibility phase, you define the most relevant technical architectures and technologies, assess risks, and provide clear, well-documented trade-off recommendations. During development, you plan and execute R&D activities with strong rigor on performance, integrity, and reliability, while anticipating technical and scheduling risks. You represent R&D with internal and external stakeholders to ensure a shared vision and execution aligned with project objectives. In the product lifecycle phase, you support market follow-up and contribute to continuous improvement and product updates.

You will operate in an international environment, with real autonomy in technical decision-making and influence on strategic—not only operational—decisions. Your achievements will have a measurable impact, as Milli‑Q® products are used in laboratories worldwide to support research and healthcare. The Guyancourt site offers a modern R&D environment, a dynamic ecosystem, and opportunities to grow into broader responsibilities and technical leadership roles.
